You may be asking yourselves that very question. Now, I know of course, we have to make a living, but nobody in this room thinks that that’s the answer to the question, “Why do we work?” For folks in this room, the work we do is challenging, it’s engaging, it’s stimulating, it’s meaningful. And if we’re lucky, it might even be important.

So, we wouldn’t work if we didn’t get paid, but that’s not why we do what we do. And in general, I think we think that material rewards are a pretty bad reason for doing the work that we do. When we say of somebody that he’s “in it for the money,” we are not just being descriptive.
